ABSTRACT
BACKGROUND:
Neoadjuvant chemotherapy has become a powerful tool to convert borderline resectable (BRPC) and locally advanced pancreatic cancers (LAPC) into a resectable scenario. However, data analyzing the optimal type of therapy are scarce. In the present multicenter retrospective study, we evaluated the influence of FOLFIRINOX (FFX) and gemcitabine (GEM)-based neoadjuvant therapy on patient prognosis.METHODS:
Data on 239 patients from 7 centers across Europe was gathered using an online database. Patients having received their first cycle of chemotherapy for BRPC/LAPC before 06/2017, with a minimum follow-up of 12 months, were included in the intention-to-treat analysis.RESULTS:
Patients treated with neoadjuvant FFX (n = 135) or gemcitabine + nab-paclitaxel (GNP) (n = 38) had significantly improved radiological response according to RECIST criteria as compared to single-agent GEM (n = 16), with a partial/complete response of 59.3%, 55.3% and 6.25% respectively (p = 0.001). Treatment with FFX (n = 135) and GNP (n = 38) resulted in higher resection rates compared to GEM (73.3%, 81.6% and 43.8%; p = 0.01 and p = 0.005). Regardless of regimen, patients who were resected had significantly prolonged overall survival compared to non-resected patients (p < 0.01). Complete pathological responses (ypT0 ypN0) were predominantly observed with FFX (p = 0.01). Adjuvant GNP in addition to successful neoadjuvant therapy and surgery resulted in a trend towards improved median survival as compared to postoperative observation (47.0 vs. 30.1 months, p = 0.06).CONCLUSIONS:
Representing one of the largest studies published so far, our results reveal that patients with BRPC/LAPC should be offered either FFX or GNP to improve chances of resection and with this also survival.Key words
